JOHN DENTON, OF PATERSON, NEW JERSEY.

FLUSHING APPARATUS.

Specification of Letters Eatent.

Patented Oct. 16, 1906.

Application filed January 10, 1905. Serial No. 240,386.

T0 at whom it may concern.-

Be it known that I, JOHN DENTON, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Flushing Apparatus; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same, reference being had to the aocompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My present invention relates to flushing apparatus of the type illustrated in my United States Letters Patent No. 768,215, where, in connection with a siphon, a siphonstarting means is used which acts to lift the water in the siphons short leg up over the bend and into the long leg.

My present invention has for its object to simplify the construction and reduce the number of operating parts in a flushing apparatus, to save as much space as possible, and to make the apparatus practically noiseless and always positive and sure in action.

I have illustrated in the accompanying drawings so much of a flushing apparatus as is necessary to show my invention, wherein Figure 1 is a view substantially in vertical section throughout, and Fig. 2 is a view illustrating a detail. I

In the drawings, a designates the bottom of a flush-tank, and b a bushing screwed therein.

The siphon is constructed substantially as follows: f is a casting comprising the bend portion of the siphon. The receiving end thereof is a substantially cylindrical body (1, having a vertical opening win one side thereof leading to the bend portion proper and having its bottom open and threaded, as at 'y. The discharge end 2 thereof is threaded and carried by a section of tubing g, which has threading engaging the threading of said discharge end 2 and which is also screwed into the bushing b and forms a support for the siphon. The chamber (1 is of considerably larger diameter than any portion of the siphon relatively beyond the same. a is a tubular body threaded at its upper end, whereby it is engaged with the threading y of chamber (i, said body being of regular inside diameter from top to bottomthat is to say,

its diameter is approximately that of the chamber d. Chambers u and (1 thus make the receiving portion of the short leg of the siphon a chamber having considerable volume. In this chamber is a iston 9c, movable from its extreme lower en clear to the top thereof'i. a, so that when said piston is at its highest elevation it leaves the opening w substantially completely exposed. This piston is carried by a rod lc, which may be connected with a suitable lever (not shown) for raising it and which may be guided in the top of chamber (1. If desired, a bushing 1, arranged in the to of chamber (1, may form the guide for rod m represents holes formed in the lower portion of chamberu in such manner as to extend above piston :1: in its rest or lowest position, so that after the resetting of the piston following a flushing the short leg may be recharged. On a view to the drawings it will be seen that the bend portion of the part f is materially diverted away from the short leg. This brings the two legs close together, thusreducing space and forming an overhang, under which certain parts to be described may be accommodated. The top of the part f may be thickened up, as at h, and formed with a right-angular bore 4,, whose inner end opens downwardly into the long leg of the siphon. Into the outer end of said bore is screwed a pipe 1', bent downwardly, and on the lower end of this is arranged to slide a tube 8, fitting loosely thereon and inclosing a valve t, adapted to seat against the end of said pipe. 1 is a stem carried by the tube 8 and carrying an adjustable float 9, arranged under the overhang above referred to.

In operation when the piston is raised to its full extent the water above it in the chambers cl and u is forced through opening w into the bend portion of the siphon, and the resultant reduction of pressure causes the water in the tank to follow. This action is rendered of full effect, because the piston in its upper position perfectly clears the opening to. As the level of the water lowers, float q falls, opens valve 25, and thereby permits air to enter pipe and discharge into the siphon, thus preventing gurgling. The efliciency of this part of the apparatus is largely dependent upon the disposition of the inner end of bore a, whereby the air discharges into the siphon in the same direction as that of the waterflow.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. In a siphon flushing apparatus, the combination of a hollow casting comprising the bend portion of the siphon and having its receiving end portion an integral chamber open at the bottom and also having an opening in the side thereof leading to the bendportion, said casting having its discharge end portion opening downwardly and disposed the bend portion of the siphon and having at ing its its receiving end portiona downwardly-opening chamber, said casting having its discharge end portion also opening downwardly and disposed close to said chamber and havend ortion diverted or offset in the direction of ow from said chamber and thus forming an overhang, a piston movable vertically in said chamber, means for moving the piston, an air-inlet device having its discharge portion opening into said casting toward the discharge end thereof, and comprising a downwardly-extending tube disposed close to the casting, and a water-operative controlling means for said inlet device depending therefrom and arranged under said overhang, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of December, 1904.

JOHN DENTON.
